TRACE ELEMENT COMPOSITION OF MEDICINAL PLANTS OF PRIMORSKY TERRITORY

Abstract

The plants growing in the Primorsky Territory are widely used in modern medicine. Traditional medicine uses xylo-phytes and herbaceous native species of plants. Methods. The researchers determined the content of some trace elements in higher wild plants collected in the Primorsky Territory: Dahurian rose, Schizandra chinensis, spiny Eleuterococcus, celandine Asian, plantain Asian. Results. Iron and aluminium dominated by the concentration level in all plant organs. The highest content of barium noted in plantain leaves and Eleuterococcus roots, iron and manganese - in rose hips and Schizandra, zinc - in the plantain aerial part, in flowers and fruits of celandine, copper - in the generative organs of herbaceous plants, the fruits of Schizandra. Higher concentrations of lead and cadmium found in herbaceous plants. The concentration of arsenic exceeded the element’s known proportion for terrestrial plants by 4-12 times. Selenium concentration in the plants from the central districts of Primorsky Territory was significantly higher than described optimum level. Conclusions. The common law confirmed for the researched plants: the concentration levels of essential elements in the organs were higher than the poportion of elements revealing toxic properties. The concentration of the latter did not exceed hygienic standards. Thus, plants growing in the Primorsky Territory can be used as a crude drug.
